Actually quite helpful

While this app does not do much automatically for you, it is still a very helpful tool in determining what is on your network and pinpointing which device is which. In the “inspector” window (on the right when selecting a specific device from the list of found items) it shows you a ot of helpful details. Perhaps the most helpful for me was the Manufacturer detail. Only 2 or 3 out of the 15 or so devices that were curently connected showed “unknown”. The majority of the rest were pretty obvious like “Apple”, “Belkin” or “Samsung”. You can label each item with your own description which helps by process of elimination if you are trying to pinpoint a device. If left with a few unknowns, just unplug a device known to be connected, but yet unidentified, and and re-scan to see which one disappeared. Overall with a little effort this app helped me label all the devices on my network and I’m not sure how else I would have done that. It might be nice if the app would guess certain devices to give you a little more of a head start, but it’s fine that it doesn’t.

I always wondered who was using my wifi

On start-up, this app tells which devices are using your internet and includes the router. It can identify some of them by manufacturer but not all. So, like many reviewers say, you need to identify which are which. The good thing is that once you identify a device, you can type in a description such as “My I-Pad” and choose the kind of device. In this case, tablet. After you have your devices identified, you can always check to see if an unknown device is using your network.

So, yes, you have to spend time to set it up. It took me about 20 minutes to identify eight devices by turning them off and on. After that, it’s done and you don’t need to just wonder if your neighbors or someone else is logged in as well.

Memory leak, needs new name

Essentially this is a solid program, but it is a much more useful program than it’s name implies. It can be used to detect any clients across a network, not just WiFi. The name is a little rinky dink and honestly undersells the program. Also, after running the program for a few days it was at over 3 GB memory utilization. This is why I do not use this product anymore, but hopefully that will be fixed in a future update. Still useful, but I wouldn’t run it on startup due to the memory issue. Implement better garbage cleanup for memory and this will be a 100% app.
